We’re well aware that lobster is king in Maine, but there’s already plenty of that around. (You could probably throw a stone from any food truck and hit a restaurant selling lobster rolls.) Besides, no truck is surrounded by more excited patrons than Urban Sugar. One of the first sweets-sellers on this list, Urban Sugar has earned its slot thanks to a whole host of hot and fresh bite-sized, gourmet doughnuts. (Because everyone knows “bite-sized” means “fewer calories,” so you’re allowed to have two or 20.) The traditional flavors are cinnamon sugar and classic sugar sprinkles, and the mini dips include glazed, chocolate, maple, and lemon — but you’d be doing yourself a disservice if you don’t opt for one of the signature bites. Whether it’s “The Lucy” (chocolate cream, chocolate sauce, and chocolate graham crumble), the “Southern Sugar” (with maple bourbon and candied pecans), or whatever the weekly special happens to be, you’ll walk away with a smile on your face — and probably some sugar and frosting, too.
